A. BACKGROUND OF THE STUDY

Cockroaches are one of the most commonly noted pest

insects due to their population. More than 3000 species

live in tropical regions. They are abundant in and aroud

dwellings in temperate areas. Cockroaches are also the

vectors for disease transmission. 

To control this pests, chemical or synthetic insecticides

are usually in many households. This insecticide has

many disadvantages because this can pose danger in

our environment like air pollution. 

This study uses onion nad calamansi extract to control

the cockroaches in the house. The extract from onion

revealed the presence of propanethial S-oxide and the

juice from calamansi contains limonens which can kill

insects.

Today, we can see the slowly killing of mother nature.

Desturction are everywhere, Air, Water and even land

pollution. We have no escape. As a student, we should

be aware of what is happening in our environment and

society and do something, in our smallest little ways, to

help preserve our only home. We are given an

INVESTIGATORY PROJECT in our physics class to

somehow lessen our environmental problem. Our project

to be investigated is the HOMEMADEOR NATURAL

INSECTICIDE. We all know, that our Ozone layer is

getting thinner and thinner every time because of the

chemicals we use daily. Now, to lessen the problem in

our ozone layer, we are going to study about the use of

natural insecticide. We can not only protect and help

preserve our environment, we can...
